Erika, a track and field club member who was told she was on the borderline for participating in the big tournament, applied to join an intensive training camp. However, upon arriving at the camp site, only Erika and her coach were there. Taking advantage of the absence of other club members, the coach began to touch Erika's body lewdly as she sat on an air chair. Seeing that Erika couldn't resist, the coach pressed the tip of his penis against her vaginal opening, claiming it was to help her endure the air chair… Erika desperately tried not to lower her hips, but eventually reached her physical limit and was slowly penetrated one centimeter at a time.
